Print Processing Using Audio Control Device 101

In the system illustrated in FIG. 1, print processing using the audio control device 101 is performed. To perform print processing using the audio control device 101, it is necessary to perform registration processing for enabling the management server 102 to manage the apparatuses in association with each other. The registration processing will be described below with reference to the sequence diagram illustrated in FIG. 6. In this sequence, processing performed by each apparatus is implemented when the CPU of the apparatus executes a program stored in the ROM of the apparatus. The program executed by the terminal device 105 is an audio control application.

The registration processing for enabling the management server 102 to manage the apparatuses in association with each other will be described below.

Before the registration processing is performed, the user logs in to the user account for the audio control device 101 managed by the management server 102 (hereinafter referred to as a first account), by using the audio control application of the terminal device 105. Thus, the management server 102 manages the terminal device 105 and the first account in association with each other. As a result, the management server 102 recognizes information about the audio control application of the terminal device 105 associated with the first account. The terminal device 105 recognizes information about the first account, including the account name, identifier (ID), and password.

In step S601, upon reception of a predetermined operation from the user, the audio control device 101 enters a mode for performing the registration processing. More specifically, the audio control device 101 enables its own access point.

In step S602, the terminal device 105 receives a registration processing execution instruction from the user as an input to a screen displayed by the audio control application.

In step S603, the terminal device 105 connects with the access point of the audio control device 101 via Wi-Fi.

In step S604, the terminal device 105 identifies an external access point which the audio control device 101 is to be connected with. More specifically, the terminal device 105 searches for surrounding external access points and displays a list of external access points found. Then, the terminal device 105 identifies the external access point selected from the list by the user. The method for identifying an external access point is not limited thereto. For example, the terminal device 105 may receive a list of external access points found in a search performed by the audio control device 101, from the audio control device 101 via a Wi-Fi connection. Then, the terminal device 105 may identify the external access point selected from the list by the user. Alternatively, for example, the terminal device 105 may identify the external access point with which the terminal device 105 was connected when the terminal device 105 receives a registration processing execution instruction from the user.

In step S605, the terminal device 105 transmits information about the external access point identified in step S604 and the above-described information about the first account to the audio control device 101 via a Wi-Fi connection. After transmitting information in step S605, the terminal device 105 may disconnect the Wi-Fi connection with the audio control device 101 and establish a Wi-Fi connection with the external access point identified in step S604.

In the above descriptions, the audio control device 101 receives information required for first registration processing via Wi-Fi, but the present invention is not limited to this configuration. For example, in a mode for performing the first registration processing, the audio control device 101 may enable the Bluetooth function and receive information required for the first registration processing via the Bluetooth connection with the terminal device 105.

In step S606, the audio control device 101 disables its own access point to disconnect the Wi-Fi connection with the terminal device 105. Then, the audio control device 101 connects with the target external access point via Wi-Fi based on the external access point information received from the terminal device 105. When a Wi-Fi connection with an external access point is successful, the audio control device 101 may audibly notify the user of the connection.

In step S607, the audio control device 101 accesses the management server 102 via an external access point and transmits the information about the first account received from the terminal device 105 and its own identification information to the management server 102.

In step S608, based on the received information, the management server 102 manages the audio control device 101 and the first account in association with each other. At this point, the management server 102 already manages the terminal device 105 and the first account in association with each other. In this way, the audio control device 101, the terminal device 105, and the first account are managed in association with each other in step S608.

In step S609, the terminal device 105 registers services (skills) to be used by using the audio control device 101. According to the present embodiment, since a printing service using the audio control device 101 is used, a printing service applicable to the printing apparatus 104 is to be registered. Therefore, the terminal device 105 transmits information indicating that the printing service applicable to the printing apparatus 104 was selected by the user, to the management server 102.

In step S610, based on the received information, the management server 102 manages the printing service applicable to the printing apparatus 104 and the first account in association with each other. More specifically, the printing service applicable to the printing apparatus 104 is registered.

In step S611, the terminal device 105 displays a login screen for enabling the user to log in to the user account (hereinafter referred to as a second account) managed by the relay server 103 associated with the printing service. The terminal device 105 acquires information for displaying the login screen, for example, by accessing the relay server 103 associated with the printing service. Since the user has logged in to the second account via a PC which controls the printing apparatus 104, the relay server 103 is assumed to be managing the second account and printing apparatus 104 in association with each other in advance.

In step S612, the terminal device 105 transmits the login information (including ID and password) input to the login screen, the information about the first account, and the information about the management server 102 to the relay server 103.

In step S613, the relay server 103 determines whether the received login information is correct. If the received login information is correct and login to the second account is successful, the relay server 103 accesses the management server 102 based on the received information about the management server 102. Then, the relay server 103 transmits an access token for permitting an access with the first account and the information about the second account to the management server 102.

In step S614, based on the received information, the management server 102 manages the first and the second accounts in association with each other.

This enables the management server 102 to manage each account and each apparatus in association with each other, making it possible to recognize which information is to be transmitted to which apparatus in notification processing according to the present embodiment.

The above-described processing performed by the terminal device 105 may be performed not via the audio control application but, for example, via a web browser on the terminal device 105.

Printing service execution processing for using the printing service via the audio control device 101 will be described below. FIG. 7 is a sequence diagram illustrating the printing service execution processing. Processing performed by each apparatus in this sequence is implemented when the CPU of the apparatus executes a program stored in the ROM of the apparatus. Processing performed by each apparatus in this sequence is assumed to be performed in a state where the registration processing described with reference to FIG. 6 is completed.

First of all, the user utters a first wake word corresponding to the audio control device 101 in the vicinity of the audio control device 101. Then, the audio control device 101 enters a mode for receiving a speech instruction from the user. Then, the user utters a second wake word as a printing service execution instruction for executing the registered printing service.

In step S701, the audio control device 101 receives the user's voice through the microphone 204 to receive a printing service execution instruction (second wake word).

In step S702, the audio control device 101 transmits audio data based on the speech instruction received in step S701, to the management server 102 via the Internet. When transmitting audio data, the audio control device 101 may transmit the user's voice received through the microphone 204 as it is as audio data, or convert the user's voice into text data and transmit the text data as audio data.

In step S703, the management server 102 analyzes the received audio data. More specifically, the management server 102 analyzes audio data corresponding to the second wake word to identify a registered printing service, the relay server 103 associated with the registered printing service, and the second account associated with the printing service.

In step S704, the management server 102 notifies the relay server 103 associated with the printing service of the reception of the printing service execution instruction. Information transmitted at this time includes information indicating the second account associated with the registered printing service.

In step S705, the relay server 103 identifies a request for execution of the printing service. The relay server 103 identifies the second account associated with the registered printing service and identifies which printing apparatus 104 is to be used to execute the printing service.

In step S706, the relay server 103 transmits notification information to the management server 102 to notify the management server 102 of functions executable with the printing apparatus 104 in the printing service. According to the present embodiment, since notification is to be made by both the audio control device 101 and the terminal device 105, the relay server 103 transmits notification information for the audio control device 101 and notification information for the terminal device 105. According to the present embodiment, the contents of a message to be audibly notified to the user by the audio control device 101 are determined by the notification information for the audio control device 101. More specifically, the relay server 103 controls the contents of a message to be audibly notified to the user by the audio control device 101. Likewise, the contents of a message and a graphic to be notified to the user through a screen by the terminal device 105 are determined by notification information for the terminal device 105. More specifically, the relay server 103 controls the contents of a message and a graphic to be notified to the user through a screen by the terminal device 105.

In step S707, based on the received notification information, the management server 102 transmits audio notification information for audibly notifying the user of functions executable with the printing apparatus 104 in the printing service, to the audio control device 101.

In step S708, based on the received audio notification information, the audio control device 101 audibly notifies the user of functions executable with the printing apparatus 104 in the printing service, through the speaker 201. According to the present embodiment, functions executable with the printing apparatus 104 in the printing service include the print function of causing the printing apparatus 104 to perform printing, and a status confirmation function of conforming the status of the printing apparatus 104. Thus, the audio control device 101 audibly notifies the user that the print function and the status confirmation function are available.

In step S709, based on the received notification information, the management server 102 transmits screen notification information for notifying, through screen display, the user of functions executable with the printing apparatus 104 in the printing service, to the terminal device 105 associated with the first account. Step S709 may be executed before step S707.

In step S710, based on the received screen notification information, the terminal device 105 displays on the display unit 504 a notification screen for notifying the user of functions executable with the printing apparatus 104 in the printing service. More specifically, the terminal device 105 displays a notification screen 1300 as illustrated in FIG. 13A. According to the present embodiment, the terminal device 105 notifies, through a notification screen, the user of more detailed contents than the contents audibly notified to the user by the audio control device 101. The notification screen 1300 includes an area 1301 for notifying the user of functions executable with the printing apparatus 104 in the printing service, and an area 1302 for notifying the user of contents printable by the print function. According to the present embodiment, the message included in the area 1301 is also audibly notified to the user in step S708. However, the message included in the area 1302 is not audibly notified to the user in step S708 but notified to the user only through screen notification in step S710. The notification screen 1300 may include not only messages for notifying the user of information about the printing apparatus 104 like the messages displayed in the areas 1301 and 1302 but also graphics for notifying the user of information about the printing apparatus 104.

This enables the user to grasp functions executable with the printing apparatus 104 in the printing service and start using the printing service.

Print processing using the audio control device 101 will be described below. FIG. 8 is a sequence diagram illustrating the print processing using the audio control device 101. Processing performed by each apparatus in this sequence is implemented when the CPU of the apparatus executes a program stored in the ROM of the apparatus. Processing performed by each apparatus in this sequence is assumed to be performed in a state where the printing service execution processing described above with reference to FIG. 7 is completed and where the user is aware of functions executable with the printing apparatus 104 in the printing service.

To use the print function from among functions executable with the printing apparatus 104 in printing service, the user utters a third wake word corresponding to the print function as a print instruction.

In step S801, the audio control device 101 receives the user's voice through the microphone 204 to receive a print instruction (third wake word).

In step S802, the audio control device 101 transmits audio data based on the speech instruction received in step S801, to the management server 102 via the Internet. As in step S702, the audio control device may convert the user's voice into text data and transmit the text data as audio data.

In step S803, the management server 102 transmits information based on the received audio data to the relay server 103.

In step S804, the relay server 103 analyzes the information received in step S803 to identify a request for execution of the print function.

In step S805, the relay server 103 transmits notification information for the audio control device 101 for audibly notifying the user of the types of contents printable by the print function, to the management server 102. In the present embodiment, the types of contents printable by the print function are only audibly notified to the user by the audio control device 101, but the types of contents may be notified to the user through screen notification by the terminal device 105. More specifically, the relay server 103 may further transmit notification information for the terminal device 105 for notifying, through screen display, the user of the types of contents printable by the print function.

In step S806, based on the received notification information, the management server 102 transmits audio notification information for audibly notifying the user of the types of contents printable by the print function, to the audio control device 101.

In step S807, based on the received audio notification information, the audio control device 101 audibly notifies the user of the types of contents printable by the print function, through the speaker 201.

When the user learns the types of contents printable by the print function, the user utters the name of the target content to select a content to be printed by the print function. At this time, the user may also utter print settings (number of copies to be printed, printing color settings, etc.) for printing of the content.

Then, in step S808, the audio control device 101 receives the user's voice through the microphone 204 to receive a selected content to be printed by the print function and print settings.

In step S809, the audio control device 101 transmits audio data based on the speech instruction received in step S808, to the management server 102 via the Internet.

In step S810, the management server 102 transmits information based on the received audio data to the relay server 103.

In step S811, the relay server 103 analyzes the information received in step S810 to identify the content to be printed by the print function.

In step S812, the relay server 103 generates binary format print data for printing the printing target content and a print job for instructing the printing apparatus 104 associated with the second account to print the printing target content. The generated print data is stored in a predetermined storage area of the relay server 103. The generated print job includes information for acquiring the print data stored in the predetermined storage area of the relay server 103, such as the Uniform Resource Locator (URL).

In step S813, the relay server 103 transmits, via the Internet, the generated print job to the printing apparatus 104 associated with the second account.

In step S814, based on the received print job, the printing apparatus 104 transmits a request for acquiring the print data stored in the predetermined storage area of the relay server 103, to the relay server 103.

In step S815, in response to the request received in step S814, the relay server 103 transmits the print data generated in step S812 to the printing apparatus 104. Instead of separately transmitting a print job and print data to the printing apparatus 104, the relay server 103 may transmit a print job including the print data in step S813.

In step S816, the printing apparatus 104 starts printing based on the print job and print data received. If an error occurs during printing, the printing apparatus 104 transmits status information indicating that the printing apparatus 104 is in an error state to the relay server 103.

When the printing apparatus 104 starts printing in step S816, then in step S817, the relay server 103 transmits notification information for notifying the user that the selected content is currently being printed by the printing apparatus 104, to the management server 102. According to the present embodiment, since notification is to be made by both the audio control device 101 and the terminal device 105, the relay server 103 transmits notification information for the audio control device 101 and notification information for the terminal device 105.

In step S818, based on the received notification information, the management server 102 transmits audio notification information for audibly notifying the user that the selected content is currently being printed by the printing apparatus 104, to the audio control device 101.

In step S819, based on the received audio notification information, the audio control device 101 audibly notifies the user that the selected content is currently being printed by the printing apparatus 104, through the speaker 201.

In step S820, based on the received notification information, the management server 102 transmits screen notification information for notifying, through screen display, the user that the selected content is currently being printed by the printing apparatus 104, to the terminal device 105 associated with the first account. Step S820 may be executed before step S818.

In step S821, based on the received screen notification information, the terminal device 105 displays on the display unit 504 a notification screen for notifying the user that the selected content is currently being printed by the printing apparatus 104. More specifically, the terminal device 105 displays a notification screen 1303 as illustrated in FIG. 13B. According to the present embodiment, the terminal device 105 notifies, through a notification screen, the user of more detailed contents than the contents audibly notified to the user by the audio control device 101. The notification screen 1303 includes an area 1304 for notifying the user that the selected content is currently being printed by the printing apparatus 104, and an area 1305 for notifying the user of a wake word for executing a print instruction, different from the third wake word. According to the present embodiment, the message included in the area 1304 is also audibly notified to the user in step S819. However, the message included in the area 1305 is not audibly notified to the user in step S819 but notified to the user only through screen notification in step S821.

When printing based on a print job is completed, then in step S822, the printing apparatus 104 transmits printing completion status information indicating the completion of printing to the relay server 103.

Thus, upon issuance of a speech instruction for printing to the audio control device 101 as a trigger, the printing apparatus 104 can start printing.

After step S822, based on the printing completion status information, the relay server 103 may transmit notification information for notifying the user of the completion of printing to the audio control device 101 and the terminal device 105.

Status confirmation processing for confirming the status information of the printing apparatus 104 associated with the audio control device 101 will now be described. FIG. 9 is a sequence diagram illustrating the status confirmation processing. Processing performed by each apparatus in this sequence is implemented when the CPU of the apparatus executes a program stored in the ROM of the apparatus. The program executed by the terminal device 105 is an audio control application. Processing performed by each apparatus in this sequence is assumed be performed in a state where the printing service execution processing described above with reference to FIG. 7 is completed and where the user is aware of functions executable with the printing apparatus 104 in the printing service.

To use the status confirmation function from among functions executable with the printing apparatus 104 in the printing service, the user utters a fourth wake word corresponding to the status confirmation function as an instruction for confirming the status of the printing apparatus 104 (an instruction for acquiring the status information of the printing apparatus 104).

Then, in step S901, the audio control device 101 receives the user's voice through the microphone 204 to receive an instruction for confirming the status of the printing apparatus 104 (fourth wake word).

In step S902, the audio control device 101 transmits audio data based on the speech instruction received in step S901, to the management server 102 via the Internet. As in step S702, the audio control device may convert the user's voice into text data and transmit the text data as audio data.

In step S903, the management server 102 transmits information based on the received audio data to the relay server 103.

In step S904, the relay server 103 analyzes the information received in step S803 to identify a request for execution of the status confirmation function.

According to the present embodiment, each time the status of the printing apparatus 104 or the status of ink provided in the printing apparatus 104 changes, the printing apparatus 104 transmits information about the status (status information) to the relay server 103. According to the present embodiment, the status information includes error information indicating that the printing apparatus 104 is in an error state, and ink information (recording agent information) indicating the status of ink provided in the printing apparatus 104.

For example, each time the status of the printing apparatus 104 changes from the normal state (no error occurrence) to an error state, the printing apparatus 104 transmits the status information indicating that the printing apparatus 104 is in an error state to the relay server 103. For example, each time the status of the printing apparatus 104 changes from an error state to the normal state, the printing apparatus 104 transmits the status information indicating that the printing apparatus 104 is in the normal state to the relay server 103.

For example, each time the status of ink provided in the printing apparatus 104 changes from the normal state (remaining amount of ink is sufficient) to the small-ink-amount state (remaining amount of ink is small), the printing apparatus 104 transmits the status information indicating the status of ink provided in the printing apparatus 104 to the relay server 103.

Then, each time the relay server 103 receives the status information, the relay server 103 updates the currently retained status information and identifies the latest status of the printing apparatus 104 associated with the second account.

In step S905, the relay server 103 generates notification information based on the currently retained status information. According to the present embodiment, since notification is made by both the audio control device 101 and the terminal device 105, the relay server 103 generates notification information for the audio control device 101 and notification information for the terminal device 105.

Upon reception of a request for status confirmation, the relay server 103 may request the printing apparatus 104 for the latest status information and acquire new status information. In this case, notification information is generated based on the new status information acquired.

According to the present embodiment, when the relay server 103 identifies that a plurality of errors is occurring in the printing apparatus 104 based on the status information, notification information to be generated differs according to the priority set for each error. A specific method for generating notification information will be described below.

In step S906, the relay server 103 transmits the generated notification information to the management server 102.

In step S907, based on the received notification information, the management server 102 transmits audio notification information for audibly notifying the user of the status of the printing apparatus 104 to the audio control device 101.

In step S908, based on the received audio notification information, the audio control device 101 audibly notifies the user of the status of the printing apparatus 104 through the speaker 201. A specific notification method will be described below.

In step S909, based on the received notification information, the management server 102 transmits screen notification information for notifying, through screen display, the user of the status of the printing apparatus 104, to the terminal device 105 associated with the first account. Step S909 may be executed before step S907.

In step S910, based on the received screen notification information, the terminal device 105 displays a notification screen for notifying the user of the status of the printing apparatus 104 on the display unit 504. A specific notification method will be described below.

Thus, upon issuance of a speech instruction to the audio control device 101 as a trigger, the user can confirm the status of the printing apparatus 104.

FIG. 10 is a flowchart illustrating processing performed by the relay server 103 in the status confirmation processing. The processing illustrated in this flowchart is implemented when the CPU 301 of the relay server 103 executes a program stored in the disk apparatus 302 of the relay server 103.

In step S1001, the CPU 301 receives from the management server 102 information transmitted based on a speech instruction for status confirmation to the audio control device 101.

In step S1002, the CPU 301 analyzes the currently retained status information of the printing apparatus 104 to identify the status of the printing apparatus 104. The status of the printing apparatus 104 includes an error state (an error occurrence), the normal state (no error occurrence), and a state where printing is currently being performed based on a print job. According to the present embodiment, an error state refers to a state where the printing apparatus 104 is unable to perform printing. Error states include a cover open state, paper jam state, out-of-paper state, busy state, and offline state. The cover open state refers to a state where a cover (not illustrated) is opened when an ink cartridge is attached to the printing head included in the printing apparatus 104. The paper jam state refers to a state where paper (recording medium) jams in the conveyance path. The out-of-paper state refers to a state where the printing apparatus 104 holds no paper. The busy state refers to a state where the printing apparatus 104 is performing non-print processing (for example, scan processing for reading a document and generating image data). The offline state refers to a state where power is not supplied to the printer unit 401 (or power supply is restricted). Error states may include a small-ink-amount state where the printing apparatus 104 holds a small amount of remaining ink (recording agent), an out-of-ink state where the printing apparatus 104 holds no ink, and a small-paper-amount state where the printing apparatus 104 holds a small amount of paper. If a plurality of errors occurs in the printing apparatus 104, a plurality of error states is identified in step S1004.

In step S1003, the CPU 301 determines whether the status of the printing apparatus 104 identified in step S1002 is an error state. When the CPU 301 determines that the status of the printing apparatus 104 is an error state (YES in step S1003), the processing proceeds to step S1004. On the other hand, when the CPU 301 does not determine that the status of the printing apparatus 104 is an error state (NO in step S1003), the processing proceeds to step S1008.

In step S1004, the CPU 301 determines whether a plurality of errors occurs in the printing apparatus 104 (whether a plurality of error states was identified in step S1002). When the CPU 301 determines that a plurality of errors occurs in the printing apparatus 104 (YES in step S1004), the processing proceeds to step S1005. On the other hand, when the CPU 301 does not determine that a plurality of errors occurs in the printing apparatus 104 (NO in step S1004), the processing proceeds to step S1007.

In step S1005, the CPU 301 identifies the priority of each of the plurality of error states identified in step S1002. More specifically, the CPU 301 first refers to a priority table as illustrated in FIG. 11. The priority table is stored in the database 313. The priority table defines the priority of each error state. The CPU 301 identifies the priorities of the plurality of error states identified in step S1002 based on the priorities defined in the priority table. According to the present embodiment, the cover open state, paper-jam state, out-of-paper state, busy state, and offline state are assigned priorities decreasing in this order. For example, if the plurality of error states includes the cover open state, out-of-paper state, and offline state, the priority of the cover open state is the highest, the priority of the out-of-ink state the second highest, and the priority of the offline state is the lowest. The contents of priorities and error states defined in the priority table may not be limited to the above-described configuration, and may be arbitrarily defined.

In step S1006, based on the status of the printing apparatus 104 identified in step S1002 and the priority of each error state identified in step S1005, the CPU 301 generates notification information about the error state of the printing apparatus 104. More specifically, the CPU 301 generates notification information so that an error state assigned a higher priority may be more preferentially notified to the user by the audio control device 101 and the terminal device 105. More specifically, the CPU 301 generates notification information so that only the error state assigned the highest priority, among the plurality of error states identified in step S1002, is notified to the user and error states other than the error state assigned the highest priority are not notified to the user. As described above, according to the present embodiment, notification is made by both the audio control device 101 and the terminal device 105 based on the notification information. Thus, the CPU 301 generates notification information for the audio control device 101 for audibly notifying the user of the status of the printing apparatus 104, and notification information for the terminal device 105 for notifying the user of the status of the printing apparatus 104 through screen display. As illustrated in the table illustrated in FIG. 11, for each error state notified, a message for notifying the user of the error state is defined. The notification information for the audio control device 101 is notification information used by the audio control device 101 to utter the target message. The notification information for the terminal device 105 is notification information used by the printing apparatus 104 to display a notification screen including the target message. The target message may include not only a message for notifying the user of an error state of the printing apparatus 104 but also a message for resolving the error state of the printing apparatus 104. For example, a message uttered by the audio control device 101 may differ from a message displayed by the terminal device 105; in particular, the message displayed by the terminal device 105 may include a message for resolving the error state of the printing apparatus 104 that is not included in the message uttered by the audio control device 101. Then, the processing proceeds to step S1009.

The present invention is not limited to this configuration. All of the error states identified in step S1002 may be notified to the user as long as an error state assigned a higher priority is more preferentially notified to the user by the audio control device 101 and the terminal device 105. More specifically, for example, notification information may be generated so that an error state assigned a higher priority may be audibly notified to the user before an error state assigned a lower priority, or a screen indicating an error state assigned a higher priority is displayed before a screen indicating an error state assigned a lower priority.

In step S1007 which is executed when the CPU 301 does not determine that a plurality of errors occurs in the printing apparatus 104 (NO in step S1004), the CPU 301 generates notification information about the error state of the printing apparatus 104 based on the status of the printing apparatus 104 identified in step S1002. Since only one error occurred in the printing apparatus 104, both notification information for the audio control device 101 and notification information for the terminal device 105 are generated so that the error state related to the one error is notified to the user. Then, the processing proceeds to step S1009.

In step S1008 which is executed when the CPU 301 does not determine that the status of the printing apparatus 104 is an error state (NO in step S1003), the CPU 301 generates notification information about the error state of the printing apparatus 104 based on the status of the printing apparatus 104 identified in step S1002. Since no error occurred in the printing apparatus 104, both notification information for the audio control device 101 and notification information for the terminal device 105 are generated so that a non-error state (normal state) of the printing apparatus 104 is notified to the user. Then, the processing proceeds to step S1009.

According to the present embodiment, when the printing apparatus 104 is in an error state, the error state of the printing apparatus 104 is audibly notified to the user and then information about ink provided in the printing apparatus 104 is audibly notified to the user. According to the present embodiment, the printing apparatus 104 is assumed to be provided with ink of four colors: black, cyan, magenta, and yellow. Therefore, information about ink provided in the printing apparatus 104 is notified to the user for each color.

In step S1009, the CPU 301 identifies the status of ink (ink status) for each color included in the printing apparatus 104. Ink states include the out-of-ink state, small-ink-amount state 1, small-ink-amount state 2, and normal state. The out-of-ink state refers to a state where the amount of ink is smaller than a first amount. The small-ink-amount state 1 refers to a state where the amount of ink is larger than the first amount and smaller than a second amount. The small-ink-amount state 2 refers to a state where the amount of ink is larger than the second amount and smaller than a third amount. The normal state refers to a state where the amount of ink is larger than the third amount. Therefore, the normal state, small-ink-amount state 2, small-ink-amount state 1, and out-of-ink state indicate amounts of ink provided in the printing apparatus 104 decreasing in this order. The out-of-ink state, small-ink-amount state 1, and small-ink-amount state 2 can also be regarded as error states related to ink of the printing apparatus 104.

In step S1010, the CPU 301 identifies the priority of each color ink. More specifically, the CPU 301 first refers to the priority table as illustrated in FIG. 12. The priority table is stored in the database 313. The priority table defines the priorities of ink states. The CPU 301 identifies the priority of each color ink based on the priorities defined in the priority table. According to the present embodiment, the out-of-ink state, small-ink-amount state 1, small-ink-amount state 2, and normal state are assigned higher priorities in this order. For example, in a case where the black ink is in the out-of-ink state, the cyan and magenta ink is in the small-ink-amount state 1, and the yellow ink is in the normal state, the black ink is assigned the highest priority, the cyan and magenta ink are assigned the second highest priority, and the yellow ink is assigned the lowest priority. The priorities and error states defined in the priority table are not limited to the above-described configuration and may be arbitrarily defined. In a case where ink of colors other than black, cyan, magenta, and yellow is held by the printing apparatus 104, priorities are also identified for the ink of colors other than black, cyan, magenta, and yellow.

In step S1011, based on the ink state of each color ink and the priorities identified in step S1007, the CPU 301 generates notification information about each color ink provided in the printing apparatus 104. More specifically, the CPU 301 generates notification information so that the ink state of an ink color assigned a higher priority is more preferentially notified to the user by the audio control device 101 and the terminal device 105. More specifically, the CPU 301 generates notification information so that the ink state of an ink color assigned a higher priority is audibly notified before the ink state of an ink color assigned a lower priority. The CPU 301 generates notification information so that the ink state of an ink color assigned a higher priority is displayed at a higher position in the notification screen than the ink state of an ink color assigned a lower priority. The CPU 301 may generate notification information so that only the ink state of the ink color assigned the highest priority is notified to the user, and the ink states of ink colors other than the ink color assigned the highest priority are not notified to the user. In a case where there exists a plurality of inks of colors assigned the highest priority, the CPU 301 generates notification information so that the ink states of the ink colors assigned the highest priority are more preferentially notified to the user over ink states of ink colors other than the ink colors assigned the highest priority. Both notification information for the audio control device 101 and notification information for the terminal device 105 are also generated as notification information about each color ink. As illustrated in the table illustrated in FIG. 11, for each ink state notified, a message for notifying the user of the ink state is defined. The notification information for the audio control device 101 is notification information used by the audio control device 101 to utter the target message and ink color. The notification information for the terminal device 105 is notification information used by the printing apparatus 104 to display a notification screen including the target message and ink color. The target message may include not only a message for notifying the user of the ink status of the printing apparatus 104 but also a massage for notifying the user of identification information such as the part number of ink. For example, a message uttered by the audio control device 101 may differ from a message displayed by the terminal device 105. In the present embodiment, a message for notifying the part number of ink is not included in a message uttered by the audio control device 101 but included in a message displayed by the terminal device 105. This is because, in many cases, information about the part number of ink includes an enumeration of alphanumeric characters, making it difficult for the user to correctly grasp the part number of ink audibly notified.

The present invention is not limited to this configuration. Notification information may be generated so that only the ink state of an ink color assigned a higher priority is notified to the user and the ink state of an ink color assigned a lower priority is not notified to the user.

According to the present embodiment, when the ink states of all the ink colors are the normal state, the CPU 301 generates notification information indicating that the ink states of all the ink colors are the normal state. When the ink state of ink of any one color is not the normal state, the CPU 301 generates notification information so that the ink states of ink colors in the normal state are not notified to the user. However, the present invention is not limited to this configuration. Even when the ink state of ink of any one color is not the normal state, the CPU 301 may generate notification information so that the ink states of ink colors in the normal state are notified to the user.

In step S1012, the CPU 301 transmits notification information about the error state of the printing apparatus 104 and notification information about each color ink generated to the management server 102.

Upon reception of the notification information, the management server 102 transmits the notification information for the audio control device 101 to the audio control device 101 associated with the first account. Then, the audio control device 101 audibly notifies the user of the status information based on the received notification information. More specifically, the audio control device 101 audibly notifies the user of the status information based on notification information about the error state of the printing apparatus 104 and then audibly notifies the user of the status information based on notification information about each color ink. For example, in a case where notification information includes notification information for notifying the user that the printing apparatus 104 is in the cover open state and notification information for notifying the user of the ink states of the yellow and magenta ink, for example, the audio control device 101 utters a message “Printer cover is open. Close the cover. The following ink ran out: Magenta. The amount of the following ink is small: Yellow”. For example, in a case where notification information includes notification information for notifying the user that the printing apparatus 104 is in the normal state and notification information for notifying the user that the ink states of all the ink colors are the normal state, for example, the audio control device 101 utters a message “Printer is in the normal state. The amount of ink is sufficient for all the ink colors”.

Upon reception of notification information, the management server 102 transmits notification information for the terminal device 105 to the terminal device 105 associated with the first account. Then, the terminal device 105 displays a notification screen based on the received notification information on the display unit 504. According to the present embodiment, the terminal device 105 notifies, through a notification screen, the user of more detailed content than the content audibly notified by the audio control device 101. FIG. 13C illustrates an example of a notification screen displayed on the display unit 504 when the notification information includes notification information for notifying the user that the printing apparatus 104 is in the cover open state and notification information for notifying the user of the ink states of the yellow and magenta ink. A notification screen 1306 includes an area 1307 for notifying the user of the error states of the printing apparatus 104, and an area 1308 for notifying the user of the ink state of ink provided in the printing apparatus 104. According to one embodiment, the message included in the area 1307 is also audibly notified to the user by the audio control device 101. The area 1307 may include an error of lower priority that is not audibly notified to the user by the audio control device 101. In that case, the area 1307 includes a message not audibly notified to the user by the audio control device 101 but notified to the user only through screen notification by the terminal device 105. The notification screen may include not only messages for notifying the user of information about the printing apparatus 104 but also graphics for notifying the user of information about the printing apparatus 104.

According to the present embodiment, a message related to the printing apparatus 104 can be notified to the user in response to a speech instruction from the user to the audio control device 101.

According to the present embodiment, the audio control device 101 audibly notifies the user of a message related to the printing apparatus 104, and at the same time the terminal device 105 notifies the user of a message related to the printing apparatus 104 through a notification screen. An audio notification enables the user, for example, to grasp a message related to the printing apparatus 104 even while the user is performing other works. A notification through a notification screen enables the user to confirm the status of the printing apparatus 104 not only through audio notification but also through screen notification. More specifically, for example, a message related to the printing apparatus 104 can be notified to both a user in the vicinity of the audio control device 101 and a user apart from the audio control device 101. For example, a message related to the printing apparatus 104 can be notified to both a user who failed to hear an audio message uttered by the audio control device 101 and a user who wants to confirm a notification again after an audio message is uttered by the audio control device 101 if the user confirms a notification screen.

The user generally needs to be notified of more detailed information as much as possible. However, if there is a large amount of information to be audibly notified to the user, the user may fail to hear audio messages, possibly being unable to correctly recognize the information notified. However, the user is able to correctly recognize the information notified even if a large amount of information is notified to the user through screen display. According to the present embodiment, therefore, a message related to the printing apparatus 104 is audibly notified to the user and at the same time a message not audibly notified is notified to the user through a notification screen. Control according to the present embodiment reduces the amount of information to be audibly notified, enabling the user to correctly recognize the information. This control further enables the user to confirm detailed information through a notification screen. More specifically, the control enables the user to correctly recognize the information audibly notified and at the same time enables notifying the user of detailed information through a notification screen.

According to the present embodiment, if a plurality of errors occurs in the printing apparatus 104, not all of the plurality of errors are notified to the user through audio notification information but only errors assigned a high priority are audibly notified to the user. This enables audibly notifying the user of only important information and enables the user to correctly recognize the information audibly notified.

In the above-described embodiments, both the error states of the printing apparatus 104 and the ink states of the ink colors provided in the printing apparatus 104 are notified to the user according to a status confirmation instruction issued by the user, but the present invention is not limited to this configuration. For example, either the error states of the printing apparatus 104 or the ink states of the ink colors provided in the printing apparatus 104 may be notified to the user. For example, in a case where a word for confirming the error states of the printing apparatus 104 and a word for confirming the ink states of the ink colors provided in the printing apparatus 104 are distinguished from each other, from among the error states of the printing apparatus 104 and the ink states of the ink colors provided in the printing apparatus 104, a state corresponding to the word issued in a status confirmation instruction by the user may be notified to the user.

The above-described examples describe messages indicating identification information of ink of which the ink state is notified, as information (hereinafter referred to as specific information) not included in information audibly notified to the user by the audio control device 101 but included in information notified to the user through a notification screen displayed by the terminal device 105. However, the specific information is not limited thereto and may be, for example, information (a link to the target screen) for displaying a screen for prompting a user to purchase the ink of which the ink state is notified. For example, the specific information may be a message indicating details of the remaining amount of the ink of which the ink state is notified. For example, the specific information may be not only information about ink but also information about the error states of the printing apparatus 104. More specifically, the specific information may be a message and a graphic indicating a method for canceling the error state of the printing apparatus 104. In the above-described examples, information about the error and ink states assigned a low priority are not notified to the user, but the present invention is not limited to this configuration. For example, information about the error and ink states assigned a low priority are not audibly notified but notified through a notification screen, and information about the error and ink states assigned a low priority may be handled as the specific information.

In the above-described example, the printing apparatus 104 has a plurality of types of ink, but the present invention is not limited to this configuration. For example, if the printing apparatus 104 is a monochrome printer, the printing apparatus 104 may have only one type of ink (black ink). In this case, information about ink notified is information about only the black ink. For example, if the printing apparatus 104 is an electrophotographic printer, information about toner may be notified to the user instead of information about ink.

In the above-described examples, the audio control device 101 does not include a display unit, but the present invention is not limited to this configuration. The audio control device 101 may include a low-performance display unit or a small-size display unit, instead of a high-performance display unit or a large-size display unit, for presenting simple information to the user, the simple information being contents of a notification transmitted from the printing apparatus 104. If the audio control device 101 includes a high-performance display unit or a large-size display unit, the audio control device 101 may display a screen related to a notification transmitted from the printing apparatus 104 on the display unit provided on the audio control device 101.

In the above-described examples, the relay server 103 generates notification information for determining the contents to be audibly notified to the user by the audio control device 101 and notification information for determining the contents to be notified to the user through a screen by the terminal device 105, but the present invention is not limited to this configuration. For example, the notification information may be generated by the printing apparatus 104 and the management server 102 and then transmitted from the printing apparatus 104 and the management server 102.
